4 Claims.

This invention relates to devices for making a permanent wave or curl in human hair, and more particularly to an improved clip for use with such devices.

The clip of the invention is designed for hair waving equipment and comprises a mandrel about which a part of the hair is wound, and a heating pad for enclosing the curled hair. The clip is used to compress the heating pad on the hair for the waving process. A laminated waterproof wrapper lined internally with absorbent material is included in the combination to prevent moisture from harming the clip.

In accordance with the invention, the improved hair clip is comprised essentially of three sections, namely a center bridge and two jaws hingedly connected with the bridge. The jaws are arranged to clamp the heating pad more evenly and securely against the wound hair. Moreover, the leverage from the center bridge to the lower end of the jaws is made relatively short whereby less spring tension is required to accomplish the necessary clamping action. Also, the jaw pressure at the neck of a hair section being treated is more direct than in prior devices, resulting in greater stability of operation.

The springs for urging the jaws towards each other in the clip of the invention need not be as strong as in prior devices, thus facilitating handling of the clip. The improved clip also comprises a flat spring interposed between the finger plates for manipulating the jaws. This flat spring may be either U-shaped or W -shaped, and prevents complete collapse of the jaws when the device is not being used.

It is accordingly an object of the invention to provide an improved three-section clip with a center bridge and two jaws hingedly connected therewith.

Another object of the invention is to provide an improved hair clip requiring less spring tension than prior devices; that will uniformly and securely press the heating pad against hair wound on a mandrel; and that is stable in operation.

Still another object of the invention is to provide an improved clip of the character referred to which is provided with a flat spring to prevent complete collapse of the jaws.

These and further objects of the invention will become more evident in the following description of preferred embodiments of the invention illustrated in the drawings, wherein:

Fig. 1 is a view in perspective of my improved hair clip.

Fig. 2 is a cross-sectional view of the clip of Fig. 1 on an enlarged scale, the clip being shown in connection with a complete hair waving equipment.

Fig. 3 is a side elevational view of the hair clip of Fig. 1.

Fig. 4 is a top View of the clip.

Fig. 5 is a perspective View of another embodiment of the invention.

Fig. 6 is an end view, on an enlarged scale of the clip of Fig. 5 withsome parts broken away.

Referring to the drawings and more particularly to Figs 1 to 4, my improved hair clip comprises a curved center bridge I0. Two arcuate jaws II and I2 are hingedly connected with the center bridge Ill on pins I3 and It. Two handles or finger plates I5 and I6 serve to manipulate jaws II and I2. Finger plates I5 and It may be of Bakelite or other suitable material. Jaw H comprises an upwardly extending portion Il secured to finger.'plate I5 by a suitable screw or rivet I8. Jaw I2 comprises a similar upwardly extending portion 20 similarly secured by'a screw or rivet to finger plate It.

A coil spring 24 embraces hinge pin l3. One free end 25 of coil spring 24 presses against jaw Il,.while the other free end 26 thereof presses against center bridge l0. Similarly a coil spring 21 is provided with two free ends 30 and 3|.

Spring end 30 presses against jaw I2, while free II and I2 when no pressure is applied on finger plates I5 and I6. Jaws II and I2 each have an outwardly curved clamping edge 34.

The operation of my improved clip is shown in connection with cross-sectional Fig. 2. A section of the hair to be waved is wound about a suitable mandrel 35. When the hair is thus wound it forms curl 36. A heating pad 31 is wrapped about mandrel 35, and encloses hair curl 3'5. Heating pad 3'1 carries heating material, such as an exothermic powder. The exothermic powder produces heat when a chemical reaction is initiated, as is well known. However, an electrical heating pad may instead be used. A waterproof laminated wrapper 38 encloses heatingpad 31. The interior thereof is lined with ab- The free ends 34, 34 of the pivoted jaws ll, l2

which have a relatively short leverage, produce a relatively large force at the neck 39 of curl 36 and ends of pad 31 and Wrapper 38. Such pressure afiords a stable assembly of the system during operation and use, preventing dislocation of the hair with respect to the other elements. Springs 24, 26 operate independently of the W spring 32 and cause a continuous even pressure about the cylindrically held pad 31 and wrapper 38 through the coaction of central bridge member l0 and outer jaws ll, l2.

A modification of the clip of the invention is shown in Figs. 5 and ti. The W-shaped flat spring 32 of the previous embodiment is replaced by U-shaped flat spring 45. Spring 45 has the same action as W-shaped spring 3-2 described hereinabove. U-shaped spring 45 is secured to finger plates l5 and It by rivets 33, 33. The hair clip of Figs. 5 and 6 functions in the same manalong opposite ends of said bridge member, the free ends of said side members being curved, springs pressing said free ends towards each other, a grip extending from each side member, and a fiat spring connecting said grips in a manner to partly counteract the action of said springs to prevent complete collapse of said jaws when not in use.

2. In a device of the character described, a clip comprising a center bridge of substantial width, two arcuate jaws hingedly connected along opposite ends of said bridge, a coil spring between each of said jaws and bridge urging the free ends of said jaws towards each other, a handle connected with each one of said jaws, and a flat spring joined between said handles in a manner to partly counteract the action of said coil springs to prevent complete collapse of said jaws when not in use.

3. A hair clip comprising a center bridge, two arcuate jaws pivotally connected along opposite ends of said center bridge, a coil spring on each of said jaws pressing the free jaw ends towards each other, opposed handles extending from said side member, and a W-shaped flat spring connecting said two handles in a manner to partly counteract the action of said springs to prevent collapse of said jaws when not in use.

4. A hair clip comprising a center bridge of subtantial width, two arcuate jaws hingedly on said center bridge; the free ends of said side members being curved, a coil spring on each of said jaws pressing said free ends towards each other, a handle mounted on each of said side members, and a U-shaped flat spring connected between said two handles in .a manner to partly counteract the action of said coil springs to prevent collapse of said jaws when not in use.
